9 Claims.

'I'his invention relates to mills, generally known as vertical edging mills, for rolling the edges of metal blanks suchfas slabs and the like. vAs such mills and theiruses are known to those skilled in the art, it is believed unnecessary `to go into a general description of them here. However, one of the diiliculties encountered in connection with vertical edging mills is the tendency for the blanks passing through a mill to climb upwardly on the periphery of one or both of the rolls and to thereby get out of linel with the pass of the rolling mill to which they are being delivered.

It is an object of this invention to provide a vertical edging mill in which blanks are held down on the vwork-supporting means on which they-travel through the mill.

The invention is illustrated in the accompanying drawings in which Fig. 1 is a view of the entry side of my vertical` edging mill with half of itshown in vertical section; Fig. 2 is an enlarged view of' the edging mill taken on line lII-II of Fig. l; and Fig. 3 is a diagrammatic view showing a modiiication of this invention.

Referring to Figs. 1 and 2 of the drawings, va pair of horizontally spaced housings I is rigidly mounted on a suitable foundation or bed-plate 2 with their central portions connected .by parallel horizontal rails 3 secured to opposite sides of the housings. Disposed between these rails in sliding engagement with their innerv faces is a pair of carriages 4 which are suspended from the rails by integralv lateral projections 6 that rest on the rails, as shown in Fig. 2.

The two carriages are moved toward and away from each other by means of horizontal adjusting screws 'I that are detachably connected to their outer surfaces. As shown in Fig. 1, the screw for each carriage is threadedin an interiorly threaded gear 8 journaled in the upper portion of the adjoining housing. This gear is `rotated, toV move the screw lengthwise, by a pinion S'Which is driven by a motor II mounted onl a`bracket I2 secured to the outer face of the housing. The twoedging rolls I3, which are su rted by the carriages in a manner .about l the mill, or oil the collars I4 on the lower ends of the rolls. Accordingly, means is provided for effecting relative inclination betweenthe worksupporting means and the axes of the rolls in vertical planes extending longitudinally of the work-supporting means. bodiment of the invention shown in Figs. 1 and 2 this relative inclination is obtained by tilting the rolls, as shown by the broken lines in Fig.

2, so that as the rolls rotate they constantly urgel a blank I6 down on the work-supporting tables 10 Il and I8, or against collars I4.

Each roll is normally journaledA on a substantially vertical axis in upper and lower arms `III projecting laterally from a frame 2| (Fig. 1) which is so associated with the adjoining carlo riageV I as to be rotatable on an axis transverse to the tables. For this purpose the frame is prferably slidably connected to the carriage, each carriage having an inwardly projecting portion 22'in lwhich there is a downwardly extending ar- 20 cuate groove 23 disposed in a plane substantially parallel to the longitudinal axis of the tables. 'I'he bottom of the frame is in the form of a segment 24 which is slidably disposed in this groove. The frame has an outwardly projecting portion 25 26 near its upper end provided with a down,- wardly extending ,ange 2l the lower surface of which is concave.` This iiange is slidably disposed in a cooperating recess 28 in .the upper portion of the carriage. Consequently, the frame 30 2l can be rotated relative to the carriage 4 the desired number of degrees with its ilange and segment sliding in the grooves in the carriage,

ythe arcuate grooves and anges having as their common center the point about which the frame rotates. When the two frames are thus inclined or tilted in planes substantially parallel to the longitudinal axis of the tables, the edging rolls journaled in the frames are likewise inclined relative to the tables.

To rotate or tilt the frames the upper end of each one is provided with a, toothed segment 3l "which meshes with a pinion 32 mounted on one end of a shaft 33. This shaft is journaled in a housing 30 and is turned by a worm gear 34 which 45 'is rotated by a worm 35 driven by a motor 36 mounted on a -bracket 31 attached to one side of the housing. The motors are reversible so that the frames and rolls lcan be tilted in either direction longitudinally of the tables, the direcu ,tion of inclination depending upon the direction in which blanks are passing through the edging mill.

As it may be desirable to vary the degree of inclination of the rolls` in accordance with the In the, preferred em- 5,

by clamping plates 2l (Fig. 2) bolted to the carthickness of the blank passing between them.

idly connected. 'Ihe free end of the pointer moves across a plate or dial 42 which is calibrated to indicate the number of degrees that' the edging rolls are inclined relative to the tables. These pointers are, of course, `actuated whenpinions l2 are rotated to tilt the frames and rolls.

Housing 3l is clamped on top of the carriage riage. By loosening these clamping plates the housing can be slid away from frame 2| to relmove pinion 32 from segment 3l, and the frame withitsroll canthenbeliftedbodilyfrom the carriage by a crane hook engaging eye connected to the frame.

Each edging roll is preferably driven from its lower end through universal couplings of -known design allowing ample angular disalignlnent. In the exemplary embodiment for the sake of simplicity wabbler connections are shown including a wabbler 43 rotated by a gear 44 journaled in a casing 40 secured to the lower portion of the adjoining carriage. Each gear is turned by a pinion 41 which is driven from below by a bevel gear 4l that in turn is driven by a bevel pinion 4l journaled on a horizontal axis in the casing.

The two bevelpinions for the tworolls'are .splined on a common shaft 5| which is driven from one end of the mill by a mowr 52.

In the embodiment shown in Fig. 3, each edging roll 4I is journaled on a vertical axis in ilxed bearings -connected to a horizontally adjustable carriage $2, andwork-supporting tables 63 and i4 are so mounted that they can be inclined longitudinally relative to the roll axes. This inclining of the tables may be eifectedir'i` various ways, but the upper .surfaces thereof are maintained in a commonplane atall times. 'Ihe drawings illustrate one way of inclining the tables according to which links are pivotally suspended from the opposite ends of each ta le with their lower ends pivoted to the upper arms of bell-cranks 61. 'I'he cranks are pivotally mounted on suitable supports Il, and their lower ends are all pivotally connected to a single rod 69 which may be reciprocated by a piston 1I in a iiuid pressure cylinder 12. The cranks on the two sides of the mill face in opPOsite directions so that when rod 69 is moved into the posiend of table i4 is lowered and the outer end of 'table 83 is raised. Blanks are delivered to and from the tables while the tables are in horizontal position.

The degree of inclination of the tables relative to the roll axes may be indicated on a calibrated dial 'I3 by a pointer I4 which is operated in any suitable manner from one of the bell-cranks that tilts the tables. The direction in which the tables are tilted will depend on the direction in which a blank is passing over them. Due to the relative inclination between the tables and the roll axes, blanks are held down on the tables.

According to the provisions of the patent statutes, I have explained the principle and mode of claims, the invention may be practiced otherwise than as specifically illustrated and described.
